YEOMANS, or PORTLAND, OREGON CONCRETE RAILWAY TIE Application filed September 9, 1929 .Serial No. 391,488.

My invention relates to railway ties and more particularly to railway ties made of con crete or other plastic material.

My new and improved tie may be produced at a minimum cost and will be relatively permanent. I

The tie is so shaped as to reduce the number of ties to a minimum. The ties are sufficiently large in bearing area to support trains of the heaviest wheel loadings, sufiiciently spaced apart to develop the bridging strength of the rails and have a sufficient-bearing area to sup port the loads Without undue settlement.

The invention cosists primarilyof a onepiece block having a base formed substantially in a straightlineand downwardly eX-' tending from which are aplurality of spaced 7 bars. running transversely of the base, The

object of the bars is to prevent the movement ofthe tie longitudinally. The tie is larger in cross-sectional area at its mid-section than at either end. Reinforcing is placed adjaare placed in spaced relation with each other.

' I make the ties larger-at their mid-section than at theoppositely disposed ends in order:

3 to prevent the movement of the tie within the same tapered, locks the tie relative to the bal-l last with which the same is surrounded. f I

.unit to afford the same greater supporting value, In the placing of co'ncrete ties the same constitutes, whenproperly placed and of proper weight, a road bedthat'is relatively permanent except with theoccasional realignment that is made by the section crew, and it is therefore desirable to provide arail support and fastening for the rail that may be adapted to different widths of rail base. I place holes vertically within the tie unit i of the tie in order that rails of different workmen.

ballast, asrI have found'thermaking ofthe' spaced'at different distances from the center p mechanism illustrated in Fig. 1, the same'bewidths of base may be secured to the tie. Means are provided within the base of the tie for receiving the heads of the bolts and to prevent the same turning therein. Recesses arealso provided at the top of the tie for receiving the rail clips therein. I

A further object of my invention consists in providing a tie unit that'will have a maxi mum supportingvalue and yet small enough 7 to be handled as individual units by single A further object of my invention consists in making the tie units adapted for being fastened together by fastening elements that may be adqusted from time to time for maintain ng the track in alignment and the rails inprecise spaced relationship with each 1 other. i

'Still further objects of my invention consist in providing a tie structurethat will remain fixedly positioned in alignment and one that will require a minimum of realignment and reballast adjustment.

With these and incidental objects in view, the invention consistsin certain novel features of construction and combination of parts, the essential'elements of which are set forth in the appended claims, and a-preferred formof embodiment of which is hereinafter shown with reference to the drawings'which accompany and form apart of this specification. 1

Like reference characters refer to like parts throughout the several YlGWSw I preferably form'my tie unit 1 of a single piece of concrete aggregate or: other tie structureformed-j from plastic material.. The tie:

preferably has a base 2 that lies substantially Within -a-single plane; Downwardlyextendr ing, lateral, cross bars 3 are disposed in spaced relationship uponthe base of. the tie, the purpose .of whiclris to prevent the longie tudinal movement of; the tie when placed within the road bed;v

I have found :best results are; obtained wherein the cross bars-are three innumber but I do not wish to be limited to three barsas the number and sizeof2 the same will depend uponthe character of surface to which, v the tie units are to be adapted; I preferably; fornrthe mid-section4 of my'tie greater in cross section areathan the ends and provide sloping sidewalls 5' that, taperuniformly from apoint lying just outsideof the base ofothe widest rail to beused upon thetie'. Reinforcing bars 6 are placed inspaced rela tionshipwith the baseof the tie and run: longitudinally ofthe tie. Theb'ars preferablyhave an oifset'end 7 provided at either end toincrease the supporting valueof the reinforcing steel near the ends of the same. In order that the tie may be; accommodated to rails of different weight, or to rails having different widths of base-,I provide-a plurality of holes 9 disposed at oppositely-disposed sides ofethe center-line of thetie through which fastening bolts may be passedrgfor maintaining the rail-clips inposition that; engage the rail base. I also provide a second series of holes 10 disposed, farther from-the central line of the tie in order toaccommodate rails-of; greater width of baseand to accommodate angle bars, adapted to the-rails, upon the tie surface. Recesses 11 are formed within the base of. the vtie for receiving the heads ofthe bolts thereinthat are .used for fastening the rail clips. vent the turning ofthe bolt within the respective holes when the bolt is being tightened.

These recesses areto pre-' while securing the rail clip in place. A central hole 12 runs longitudinally of the tie through which a spacer and fastening bolt 13 pass. The hole 12 is made substantially larger than that of the tie rod, or tie bolt, in order that the rod may be insulated from the tie itself, thereby lessening the. tendency of. electric shorts being developed between the tie, the rail and the ground. The reinforcing bars 6 lie outside of the bolts in order-that the tendency of electric shorts may be also lessened or reduced to a minimum. Glip receiving recesses 14 are formed within the upper surface of, the tie into which the rail'clips may be made to engage, or for maintaining the rail clips in spaced relationship wit-h the tie bodywhen a material amount of wear has occurred. between the tieand the-rail, thereby permitting the clip to be depressed within the tie surface. The depth of the recesses 14 is greater than the amount ofv normal wear that occurs within the upper. surface of the tieduring the normal lifel of the tie.

I mold. a washer .15 within'the base of the; tie body and so place the washer that the head and described is admirably adaptedto fulfill the objects primarily stated, it; is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown'and described, as it is sus-' ceptible of embodlment ln-varlous forms, all

coming within the scopeof the claims which follow.
